Subject: [MODERATED] [PATCH v7 2/5] NX 2
Date: Thu, 24 Oct 2019 09:34:12 +0200	[thread overview]
Message-ID: <1571902455-22638-3-git-send-email-pbonzini@redhat.com> (raw)
In-Reply-To: <1571902455-22638-1-git-send-email-pbonzini@redhat.com>

This patch adds new cpu family ATOM_TREMONT_D to the cpu vunerability
whitelist. ATOM_TREMONT_D is not affected by X86_BUG_ITLB_MULTIHIT. There
may be more bugs not affecting ATOM_TREMONT_D which are not known at
this point and could be added later.
